Title: Brush assembly for grounding shaft
Inventor: MAIKERU TSUWAADOCHIRIBU
IPC: H01R4/64
Filed: 1992-03-02
Abstract: PURPOSE: To provide a brush assembly in which an earthing brush is brought into contact with a rotating shaft, and non contact time relating to the bound of the brush is reduced. CONSTITUTION: A brush 70 is fixed to an arm 72 in the state that energizing force is applied to the pivotable arm 72, and even if the brush bounds by vibration or the run-out of a shaft, the brush is brought into contact again with the shaft, by energizing force. In order to reduce friction by the contact of a negater spring 86 with the pivotable arm 72, the negater spring and the arm are made in rolling contact. By rolling contact, responding capability of a brush assembly in recovering the contact with the shaft, is remarkably enhanced by decrease in friction caused by pivotable mounting of the arm for fixing the brush.

IPC: H04B10/032
Filed: 1986-04-07
Abstract: PURPOSE:To improve reliability by converting a signal on a cable into an electrical signal in an intermediate communication node and relaying it as it is instead of converting it into an optical signal again. CONSTITUTION:When an input signal is given to the input terminal IN1 of a transmission dedicated communication node NDS1, a directional joint optical modulator MD 13 passes by two communication light sources in a parallel connection state at the low level L of the input signal, whereas at a high level H said modulator MD 13 passes by the two communication light sources in a crossed connection state. An optical signal (c) is given to the input of the optical dimultiplexer F1 21 of a reception dedicated communication node NDR2, and an optical signal (d) given to the input of an F2 22. At that time, since the two optical signals are transmitted with their wavelengths lambda2 reversed each other, electrical outputs (e) and (f) can be obtained from photoelectric transducers OEC1s 23 and 24. As a result the output of the same signal can be obtained from an inverter circuit IV 25 as if the same transmission is made from an OEC2 24.

Title: Method for rolling h-shape steel with small offset of center
Inventor: HAYASHI HIROYUKI
IPC: B21B37/16
Filed: 1993-04-07
Abstract: PURPOSE:To reduce defects in dimensional accuracy especially the offset of the center by determining the deviation between respective rolls by measuring the thicknesses and leg lengths of flange of the respective flanges in four upper, lower, right and lift parts of a roughly formed steel billet to which break down rolling is executed and changing roll positions based on this deviation. CONSTITUTION:The offset amount of the center of each of the right and left flanges is calculated from the thicknesses and leg lengths of respective upper, lower, right and left flanges of the roughly formed billet in the proximity region of a roughing universal mill. From conditions that the relationship of the difference between the drafts of the upper and lower flanges and the variation of the offset of the center, the target drafts of the flanges at the following pass and the mean draft of the upper and lower parts of the respective right and left flanges are equalized, the target thickness of flange on the outlet side at the following pass so that the offset of the center comes to zero or in the allowable range is determined. Based on this target thickness of flange on the outlet side, the deviation of the respective rolls 17, 18 of the roughing universal mill is calculated and, after the positions of the respective rolls are changed based on this arithmetic result, the billet is rolled by one or more passes.

Title: Pressure controller
Inventor: INAGAKI YOSHIHIKO
IPC: F15B11/06
Filed: 1986-04-10
Abstract: PURPOSE:To keep the extent of machining pressure constant with a simple device, by installing a discharge valve and a buffer tank between the regulator secondary side of the cylinder attached to a robot arm and the cylinder, and also a tool in a piston tip as well as a teaching device altogether. CONSTITUTION:Air regulated by a regulator 1 is fed to a cylinder 2 through a buffer tank 11, operating a piston 3. As for large profiling on a work, a robot 9 is subjected to teaching, but for small projection 7a, the piston 3 goes up through a grindstone 6. And, air pressure inside the cylinder 2 temporarily goes up. However, the buffer tank 11 absorbs this sudden pressure rise. Tank capacity V1 is set so as to be settled within requisite pressure accuracy in a ratio to capacity V2 of the cylinder 2. That is to say, if V1=20V2 is the case, even if the V1 is varied as much as 50%, a pressure variation inside the cylinder 2 is controllable within the range of 25%. Thus, since machining pressure is kept constant with a simple device, an irregularity part, where teaching fails to do, is machinable without the smallest strain.

On the other hand, there is no contact between each of the hooks 43, 44 and the lower plate 11 at a resting position. The lower plate 11 is positioned according to an angular position applied to a mold piece 50 so that initial force in the direction G operating on the lower plate 11 and a movable armature 5 can be progressively adjusted because of the angular motion of the mold piece 50. In this way, initial compensation can be progressively adjusted.
